## What it is
System Informer (formerly Process Hacker) is a free, open-source, multi-purpose Windows tool for monitoring system resources, debugging software, and detecting malware. It provides detailed real-time views of processes, services, network connections, disk activity, and kernel-level system information.

## Use cases
- find which process is locking a file or DLL
- monitor CPU, memory, disk and network usage in real time
- inspect and terminate suspicious processes that Task Manager can't
- view detailed stack traces with kernel-mode and .NET support
- see which programs have active network connections and close them
- debug software and analyze potential malware behavior
- track down resource hogs and runaway processes

## When to choose
- you need a more powerful Task Manager or Process Explorer alternative on Windows
- you're troubleshooting file locks, handle leaks, or network activity
- you're a developer or security researcher inspecting process internals and stack traces
- you want an open-source, actively maintained system monitor

## When to avoid
- you're on Linux or macOS - it's Windows 10+ only
- you need a simple, beginner-friendly monitor rather than an advanced tool
- you need cross-platform or remote monitoring dashboards

## Facets
- artifact type: application
- maturity: active
- function: monitoring, benchmarking, security, developer-tools
- domain: windows, developer-tools, security, performance
- platform: windows
- tags: task-manager, process-explorer, process-hacker, system-monitor, malware-analysis, debugging, sysinternals-alternative
